1. General description
Video Grabber DisplayPort (DGR-1000) is a real-time video capturing device that works using the
DisplayPort 1.2 interface. Equipped with a passive video splitter it can be safely installed between the
computer and its screen (Pass-through connection –See 3.2, p. 8) as it doesn’t even have to be
powered on to forward the video signal to the display
1
. In cases where absolutely no interference in
the recorded signal is allowed DGR-1000 can even emulate a specific monitor and record a mirrored
video signal thus ensuring that the link between video source and the display remains untouched
(Monitor emulation –See 3.3, p. 9).
Configured either using web browser or via SNMPv3 DGR-1000 provides wide variety of possibilities:
both lossless and lossy compression algorithms are available, captured signal can be provided as RTSP
stream or saved at a user-defined network location. Support for Network Time Protocol (NTP) makes
it possible to timestamp the data at the moment of its capture.
Designed for the Air Traffic Control, DGR-1000 provides an option for power and network
redundancy.
1
Integrated video splitter requires at least 500mA on pin 20 of DisplayPort port for passive mode. It can be
provided by the monitor or graphics card (or both)

3. Device installation
3.1. Introduction
Video Grabber DGR-1000 is designed to capture and process video signal from DisplayPort 1.2
interface. While by default it is assumed that DGR-1000 is installed between the computer and its
monitor –pass-through –it can also be installed independently as an emulated monitor. See the
following sections for instructions on both approaches.
Regardless of the approach chosen it is advised to turn off all equipment involved in cable
connections (display, recorded computer and Video Grabber) for the time of the installation.
3.2. Pass-through
By default Video Grabber captures the video data that is sent by the computer to the display. It is
connected between those two devices (see figure below).
ComputerMonitor
DGR-1000
Figure 5: Pass-through connection schema
Computer is connected to the DGR-1000’s video input port, and the monitor is connected to the Video
Grabber’s video output port. As a result Video Grabber effectively captures the video signal that is
being sent by the computer to the monitor.

3.3. Monitor emulation
Computer sends the same video signal on two of its video ports. One is connected to the monitor and
the other is connected to the Video Grabber. See the connection details below.

Figure 7: Monitor emulation connection schema
One of the computer’s video outputs is connected to the DGR-1000’s video input port while the other
is connected to the monitor. When ‘Monitor emulation’ is enabled in the Video Grabber’s
configuration it is detected by the computer as a monitor and as such can be configured as a mirror of
an actual screen in the computer’s graphic card configuration.

3.5. Network connection
Video Grabber DGR-1000 has two RJ45 ports, named LAN 1 and LAN 2. When both interfaces are
configured and active (connected) then the same data is sent through both of them. This way two
independent systems can receive the same data from the Video Grabber using two physically separate
connections thus achieving redundancy.
Device can work in 10, 100 and 1000 Mbit/s network, however when higher framerates and resolutions
are in use 1000 Mbit/s network may be required to comply with higher data rates. Video Grabber
detects type of network automatically as long as network connection cable complies with network
standard CAT5e
2
or higher.
10 Mbit/s 100 Mbit/s 1000 Mbit/s
Figure 9: Indication of different port speeds on the LEDs:
10 Mbit/s –both LEDs on, 100 Mbit/s –right LED on, 1Gbit/s –left LED on
2
The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95. These
documents specify performance characteristics and test requirements for frequencies up to 100 MHz. Cable
types, connector types and cabling topologies are defined by TIA/EIA-568-B. Nearly always, 8P8C modular
connectors (often referred to as RJ45 connectors) are used for connecting category 5 cable. The cable is
terminated in either the T568A scheme or the T568B scheme. The two schemes work equally well and may be
mixed in an installation so long as the same scheme is used on both ends of each cable.

3.6. Power supply unit
Figure 10: Connecting power to the Video Grabber
Connecting Video Grabber to power source:
-Plug power supply unit to Video Grabber, make sure *click* is heard.
-Tighten the screw on the plug to secure power supply unit from unplugging.
-Power supply unit can now be connected to power source.
Video Grabber has two power inputs (PWR1 and PWR2), but requires only one power supply to work
properly. The dual power input design gives user an option of ensuring power redundancy for the
device which may be required in some systems (e.g. ATC related). When two power supplies are used
then Video Grabber balances the load on both of them. If one of them fails then Video Grabber will
continue working by using remaining power supply exclusively.
Due to the nature of DisplayPort connection when the Video Grabber locks to the recorded signal (e.g.
when it starts) a short blink on the recorded display may be observed.
Video Grabber uses 12V, 2.5A power supply, but its maximum power consumption is 12W.
